[0003] In the prior art, patent document with publication number (CN215787903U) mentions an oil pipe welding fixture for oil pipe cylinder processing, including a support base and a rubber protective layer. The top surface of the support base is provided with a positioning groove, and a limiting column is installed inside the positioning groove. The limiting column is embedded and fixedly connected to the inner wall of the support base. The limiting column penetrates a limiting straight plate, which is located inside the positioning groove. A support plate is welded and fixedly installed on the top surface of the limiting straight plate, and the top end of the support plate is sleeved on the outside of a central ring. An oil pipe clamping plate is installed inside the central ring. In this prior art, after the operator completes the clamping and fixing of the oil pipe, the support plate can be pushed to allow it to slide smoothly through the limiting straight plate, thereby shifting the oil pipe. This facilitates alignment and prevents large gaps that could affect subsequent welding operations.
